Multigrid in the simulation context

cfd enthusiast

Hello everyone,

I created a Mesh with 3 grids in the Mesh context. In the simualtion context I choose to simulate on one grid instead of all 3. Does fidelity simulate on the fine or the corase mesh if I do that?

Thank you!

    In the Fidelity Simulation user guide (v 2023.2) you can find the "Numerics Multigrid" section under "Numerical parameters". It explains what is the "current grid level" and the "number of grid levels". I understand you have put the "current grid level" to 0 (the finest) and the number of grid levels to 1, correct?

    If I misunderstood:

    • Can you share a screenshot of your Numerics tab?
    • Which version of Fidelity are you using, and which solver?
    • Can you please also show in the Mesh context your settings that provide you 3 grid levels?

    Best regards,
    Colinda
